About 2.5 inches head to tail these mallard chicks must be very young. I photographed them through the rod iron fence I've shot through before at Kissena Park here in NYC. All are hand held with Fuji X-T3, Sigma 150-600 C + Fuji 1.4x TC just above the ground with the LCD flipped facing up and used to compose. Tricky as can be yet the times I'm able to capture an image is worth the frustrations.
Re-edit of an older shot, but I was surprised to see the Pro-neg sims are now in Lightroom, thought that was kind of cool that older RAFs might benefit from that without having to buy a newer model cam just for that sim.
Nick here's a flash diffuser I made for the T4 and the longer 80mm Fuji.
As much as I like the 80mm sometimes the much smaller Laowa is just less tiring to use.
